Doh!! I just re-checked the ebay ad and scrolled down and see that the white is ground, black is 'low function' and red is 'high function'. I'll use the high, which I'm guessing it's a brake light as opposed to the low's tail light function (guessing, I said). I know if I wire it backwards, I'll know immediately to change it. I'm also guessing that just terminating the low will work. All of you smarter guys out there let me know how it's really done if this doesn't sound right. Thanks.
